Amino acids are the building blocks of proteins, which are converted by plants into new growth. Some amino acids also play a critical role in photosynthesis, the process by which carbohydrates are converted into both energy and new proteins. Humic acid is a common treatment, but amino acids are often neglected at the expense of potential plant productivity and plant resistance to environmental stresses.
